  title={Generating Deductive Database Explanations},
  author={Sarah Mallet and Mireille Ducass{\'e}},
Existing explanation systems for deductive databases show forests of proof trees. Although proof trees are often useful, they are only one possible interesting representation. We argue that an explanation system for deductive databases must be able to generate explanations at several levels of abstraction. One possible and well known technique to achieve this exibility is to instrument meta-interpreters. It is, however, not often used because of its ineeciency. On the other hand, deductive… CONTINUE READING
